The positive terminal 13 is electrically connected to the positive electrode of the energy storage module 11, and the negative terminal 14 is electrically connected to the negative electrode of the energy storage module 11. And in this embodiment, the number of positive terminals 13 on one panel 12 is two, and the number of negative terminals 14 on one panel 12 is two.

[0054] Referring to Figure 2 and Figure 3, four mounting plates 2 are fixedly connected inside the cabinet body 1. The four mounting plates 2 are respectively located at the four corners of the chamber 111. The mounting plates 2 extend along the height direction of the cabinet body 1. One end of the mounting plate 2 is fixedly connected to the upper inner wall of the chamber 111, and the other end of the mounting plate 2 is fixedly connected to the lower inner wall of the chamber 111. Mounting ears 21 are fixedly connected to the four corners of the energy storage module 11. The mounting ears 21 correspond to the mounting plates 2 one by one. A plurality of height holes 22 are formed in the mounting plates 2, and mounting holes 23 are formed in the mounting ears 21. The plurality of height holes 22 are evenly distributed along the extending direction of the mounting plates 2 to achieve distribution at different heights. The same plug-in member 24 is inserted through the height holes 22 and the mounting holes 23 to realize the installation of the energy storage module 11 inside the cabinet body 1. The plug-in member 24 can be a bolt. When the mounting holes 23 are aligned with the height holes 22 at different heights for installation, the installation of the energy storage module 11 at different heights is realized, and the distance between adjacent energy storage modules 11 is controlled to facilitate heat dissipation.

[0055] Referring to Figure 3 , a handle 3 is rotatably connected to the energy storage module 11. The handle 3 and the panel 12 are on the same side wall of the energy storage module 11. The handle 3 is rotated to be parallel to the side wall of the mounting plate 2 and rotated to a position away from the energy storage module 11 for pulling.

[0056] Referring to Figure 2 And Figure 4 And Figure 5 , a plurality of insulating seats 31 are fixedly connected to the panel 12. The insulating seats 31 are sleeved outside the positive terminal 13 or the negative terminal 14. In this embodiment, there are four insulating seats 31 on one panel 12, corresponding to two positive terminals 13 and two negative terminals 14 one by one. There is a gap between the outer circle of the insulating seat 31 and the positive terminal 13 or the negative terminal 14. A clamping block 32 is fixedly connected to the inner wall of the outer circle of the insulating seat 31. An insulating cover 33 is covered on the insulating seat 31. The insulating cover 33 is inserted into the gap between the outer circle of the insulating seat 31 and the positive terminal 13 or the negative terminal 14. An elastic ear 34 is fixedly connected to the insulating cover 33. The elastic ear 34 is made of a material with a certain elasticity, such as insulating plastic, etc. One end of the elastic ear 34 is fixedly connected to the side wall of the outer circle of the insulating cover 33, and the other end of the elastic ear 34 extends in a direction that is farther and farther away from the insulating cover 33 as it extends. A clamping groove 35 for the clamping block 32 to be inserted and clamped is formed in the elastic ear 34.

[0057] Referring to Figure 2 And Figure 6, including a data processing module 4 installed in the panel 12, and a display module 41 for displaying installed on the panel 12. The display module 41 can adopt various display screens, such as digital screens, liquid crystal screens, etc. A quality detection component 42, a light emitting component 43, and a light receiving component 44 are installed on the cabinet 1. The light emitting component 43 and the light receiving component 44 are installed on the inner wall of the chamber 111. The quality detection component 42 can adopt a pressure sensor and is installed at the position where the cabinet 1 contacts the ground. For example, if there are supporting feet at the bottom of the cabinet 1, the quality detection component 42 is installed between the lower end surface of the cabinet 1 and the supporting feet. The quality detection component 42 is used to detect the quality of the energy storage module 11 and obtain quality data.

[0058] Reference Figure 2 and Figure 6 A colored lens 45 is fixedly connected to the energy storage module 11, and the colored lens 45 is installed on the side of the energy storage module 11. The light emitting element 43 is fixedly connected to the upper inner wall of the chamber 111 and emits light downward. The light receiving element 44 is fixedly connected to the lower inner wall of the chamber 111 to receive light. The colored lenses 45 on multiple energy storage modules 11 are distributed along the same straight line and are all between the light emitting element 43 and the light receiving element 44. The light emitting element 43 emits light that passes through all the colored lenses 45 and is received by the light receiving element 44. The light receiving element 44 obtains received light intensity data. The light receiving element 44 can use a light sensor, a light intensity sensor, or other sensor that can detect light intensity. The cabinet 1 is also provided with a door opening detection member 46, which can be a travel switch and is installed on the side wall that contacts the cabinet 1 when the cabinet door 112 closes the opening surface of the chamber 111. The door opening detection member 46 is used to detect the opening and closing state of the cabinet door of the cabinet 1 and obtain a door opening signal.

[0059] Reference Figure 6 The data processing module 4 includes a processor and a database. The database is used to store various threshold data, such as single module quality threshold, single module light transmittance threshold, output threshold, series-parallel threshold, dust sweeping threshold, etc. The processor is used to receive door opening signals, light intensity data, quality data, and call corresponding threshold data from the database, obtain serial-parallel connection method signals after calculation, and output them to the display module 41 for display.

[0060] The processor may include a central processing component such as a CPU or MPU, or a host system built around a CPU or MPU, including hardware or software. After the measuring instrument is equipped with a processor, people can freely control the measuring instrument through programming to make it operate according to people's wishes. The processor can control local quantity transfer, remote quantity transfer, remote communication, etc. through internal protocols. The internal protocol generally refers to all protocols for realizing mutual communication or connection within the same measuring instrument or the same system, including: part or all of the human-computer interaction protocol, software / hardware (interface) protocol, chip bus (C-Bus) protocol, internal bus (I-Bus) protocol, etc. With the development of integrated circuit technology, some that belong to the external bus (E-Bus) protocol also belong to the internal protocol after being integrated into the chip along with the external bus (E-Bus).

[0061] The implementation principle of a household energy storage device in an embodiment of the present application is as follows: When it is necessary to install the energy storage module 11, first open the cabinet door 112, then place the energy storage module 11 into the chamber 111, align the height hole 22 with the installation hole 23, and then fix and install it through the plug-in 24. Data is collected through the quality detection component 42, the light emitting component 43, and the light receiving component 44. After calculation by the data processing module 4, it is displayed through the display module 41. The user holds the elastic ear 34 to displace, so that the clamping block 32 exits from the card slot 35. After removing the insulating cover 33, the user makes a series or parallel electrical connection between the positive terminal 13 and the negative terminal 14 among multiple energy storage modules 11 according to the display of the display module 41.

[0062] An embodiment of the present application discloses an auxiliary installation method for a household energy storage device. Refer to Figure 7 , the auxiliary installation method for a household energy storage device includes the following steps:

[0063] S1. Obtain the power supply demand data, obtain the quality data, and obtain the received light intensity data;

[0064] S11. Determine the quality quantity data through the quality data, the preset single-module quality threshold, and the preset irrelevant quality threshold;

[0065] S12. Determine the light transmission quantity data through the received light intensity data, the preset single-module light transmission threshold, and the preset transmitted light intensity threshold;

[0066] S13. Determine the module quantity data through the quality quantity data and the light transmission quantity data;

[0067] S14. Determine the series-parallel connection method signal through the module quantity data, the power supply demand data, the preset output threshold, and the preset series-parallel threshold and output it.

[0068] Details: The energy supply demand data is the currently required power supply after the user opens the door. For example, if two 5W lights need to be connected, then a power supply of 10W is required, and 10W is the energy supply demand data. Let the single-module mass threshold be 20,000N. If the mass data is 70,000N and the cabinet 1 itself is 10,000N, this is the irrelevant mass threshold and needs to be input in advance and excluded during calculation. Then the number of energy storage modules 11 can be obtained as (70,000 - 10,000) / 20,000 = 3. The single-module light transmittance threshold is the threshold data of the light transmittance of the colored lens 45, and its unit can be cd (candela, lumen, such as normal colored light) or watt (W, such as the energy of infrared rays). Let the single-module light transmittance threshold be 2mW (milliwatt). Let the transmitted light intensity threshold be 10mW. If the received light intensity data obtained is 4mW, then the light transmittance quantity data can be calculated as (10 - 4) / 2 = 3, which is the number of colored lenses 45 and also the number of energy storage modules 11. At this time, both the mass quantity data and the light transmittance quantity data are 3, so the module quantity data can be obtained as 3, that is, the number of energy storage modules 11 is calculated as 3. If the calculated mass quantity data is 3.5 and the light transmittance quantity data is 2.9, it may be that the user has placed something outside the cabinet 1, such as a screwdriver toolbox, etc., resulting in a larger mass data obtained, and the irrelevant mass threshold cannot be excluded, and dirt or dust on the colored lens 45 will cause the received light intensity data to be smaller and the light transmittance quantity data to be smaller. Then take the smaller value and round up, that is, the module quantity data is 3. The output threshold is the output power of a single energy storage module 11, and the series-parallel threshold is the different maximum output powers obtained by connecting multiple energy storage modules 11 in different connection methods such as series or parallel. If the module quantity data is 3, let the energy supply demand data be 1000W, 10A, and the output threshold be 500W, 5A. To electrically connect all the energy storage modules 11 to improve the stability and reliability of the overall system, two energy storage modules 11 need to be connected in series. At this time, the output current of the two series-connected energy storage modules 11 is 5A, and then the last energy storage module 11 is connected in parallel to the two series-connected energy storage modules 11. At this time, the overall output current is 5 + 5 = 10A. And the calculation methods such as parallel current addition, series voltage addition, power distribution, and internal resistance influence are the series-parallel thresholds. Thus, the series-parallel connection method signal is displayed through the display module 41, and the display method can be divided into multiple types. For example, it can directly display which positive terminal 13 or negative terminal 14 of which energy storage module 11 is connected to which positive terminal 13 or negative terminal 14 of which energy storage module 11 by a wire. At this time, it can directly display all at once, or it can be displayed one by one step by step, that is, display one and let the user connect one, and then display the next one after detecting that the circuit is conducting, and the user continues to connect.

[0069] Refer to Figure 8 , and also includes the following steps:

[0070] S2. Obtain the door opening signal and obtain the time data;

[0071] S21. Determine the environmental dust accumulation speed data based on the door opening signal, time data, and received light intensity data;

[0072] S22. Determine the new single-module light transmission threshold based on the original single-module light transmission threshold, environmental dust accumulation speed data, and module quantity data, and replace the original single-module light transmission threshold;

[0073] S23. Determine the cleaning signal based on the door opening signal, environmental dust accumulation speed data, preset dust cleaning threshold, and quality data;

[0074] S24. Determine the new single-module light transmission threshold based on the cleaning signal and the original single-module light transmission threshold, and replace the original single-module light transmission threshold.

[0075] Specifically: If the door opening signal indicates the door is in the closed state, if the time data is the 1st hour, and at this time if the received light intensity data is 4 mW, and if the time data is the 11th hour, and at this time if the received light intensity data is 3.9 mW, then the environmental dust accumulation speed can be obtained as (4 - 3.9) / (11 - 1) = 0.01 mW / h. Dividing by the module quantity data gives the dust accumulation speed data of a single colored lens 45, which is 0.0033 mW / h. Then, this data is used to correct the single-module light transmission threshold, that is, the original single-module light transmission threshold - 0.0033 * t gives the latest single-module light transmission threshold, where t is the time data. The new single-module light transmission threshold participates in the calculation of the light transmission quantity data, thus eliminating the influence of dust accumulation; when the door opening signal indicates the door is in the open state, at this time the user may wipe and clean the colored lens 45. If the environmental dust accumulation speed data changes suddenly, that is, if the time data is the 11th hour, and at this time if the received light intensity data is 3.8 mW, and if the time data is the 11.1th hour, and at this time if the received light intensity data is 4 mW, then the environmental dust accumulation speed is (3.8 - 4) / (11.1 - 11) = -2 mW / h. Assuming the dust cleaning threshold is -0.1 mW / h, then this indicates that the user has cleaned the colored lens 45, and a cleaning signal is output to reset the single-module light transmission threshold.

[0076] Refer to Figure 9 , and further includes the following steps:

[0077] S3. Determine the energy supply difference based on the energy supply demand data and output threshold;

[0078] S31. Determine the difference multiple data based on the energy supply difference and output threshold;

[0079] S32. Determine the series-parallel connection method signal based on the difference multiple data, series-parallel threshold, and module quantity data, and output it.

[0080] Detailed: Calculate the difference by using the power supply demand data and the output threshold. This is the power supply difference. Assume the power supply demand data is 10A and the output threshold is 5A. Then the power supply difference is 10 - 5 = 5A. The difference multiple data is 500 / 500 = 1. The output threshold is the performance of a single energy storage module 11. A difference of one time means that only one more energy storage module 11 needs to be connected in series, and the last one is connected in parallel. If the difference multiple data is 2, it means that two need to be connected in series. If the difference multiple is 0, it means that no series connection is possible and only parallel connection can be used.

[0081] An embodiment of the present application discloses a computer-readable storage medium. Refer to Figure 1 The computer-readable storage medium stores a computer program that can be loaded and executed by a processor to perform the auxiliary installation method of the household energy storage device.

[0082] The computer-readable storage medium includes, for example: various media that can store program codes such as USB flash drives, mobile hard disks, read-only memories (ROM), random access memories (RAM), magnetic disks, or optical discs.

[0083] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
